ok so you have 23 = 1-d If you are looking for d than you have to get d by itself. To do this you can do it one of two ways. you can add D to both sides to get rid of the negative d (b/c you are looking for positive d). this would leave you with 23+d=1 then to get d by itself ...

Math
if you are solving for d then all you have to do is subtract both sides by one and then divide by a negative d= -22 or add d to both sides and subtract 23 either way works
